This magical ring is made of rough hewn wood, but the wood is polished smooth from years of wear by the previous owner.
The ring is connected to five pocket dimensions. As an action, the wielder can snap their fingers and put a willing creature of the size Large or smaller in one of the five slots. Inside, the environment is adapted to suit the creature, and they are magically provided food suiting their nutritional needs. Any creature inside one of the pocket dimensions has no way of exiting on their own, and cannot communicate with the wielder except through interplanar magical communication methods. The wielder also has no way of looking inside the stable.
